To all whom it may concern:

Be it known that I, ANTON IvnRsEN SLET- 4TEN, a subject of the King of Norway, re-l sidingat Christiania, Norway, have invented certain new vand useful Improvements in Internal-Combustiony Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others :tkilled in the art to which it appertains to make and use the same, reference being hactto the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification. In Yinternal combustion engines of 4the kind provided with a hot-chamber into which is introduced a jetof oil ignited by the hot walls of the chamber, it is known to' place a deflector in the path of the' oil jet in order to direct the oil either upwards in the hot chamber or downwards into the cylinder.

Said delectors are and very liable to becoming overheated, so that part of the oil introduced is deposited in the form of carbon and slag on the deflector. This again makes it necessary to take the deflector out for cleaning at shorter or' longer intervals.

This inconvenience is obviated according tothe present invention by lacing the dellector surface on a water-,coo ed tube, which goes diametrically through the hot chamber. In the preferred form the dellector surface is worked formed in the middle of a. thickwalled water'tube, but obviously the deflecting vane or the like may also be fastened on a rod or -arm provided with water-cooling means.

On the drawing illustra-ting one form 'of the invention:

Fig. l is a vertical section perpendicularly on the water tube.

Figs. 2 and 3 are vertical and horizontal axial sections through the water tube.

The deflecting surfaces 2 are formed by cutting away the thick walls of the tube 3, so as to form substantially flat oil deflecting Surfaces that will deflect. oil when sprayed against them upwardly and downwardly, as clearly shown in Fig. l. The vtube 3 is substantially straight and extends straight through the hot chamber commonly used with' the liquid fuel type of internal combustion engine. Being straight, it is readily removable for cleaning. Being thick-Walled, the delecting surfaces 2 may be cut into the wall of the tube at the desired angle whereby deflecting surfaces are formed Without the use of any additional element.

`In order to cool the tubel 3 cooling vwater is led into one end of it and carried away from the other end by the pipes 4. In or- ,der to control the angle of deflectiony-a handle 5 may beprovided whereby the tube 3 may be. turned so as to cause the oil to be dellectedi'n the proper direction upwardly and downwardly.

Claims. l. In combination with an internal combustion engine of the type provided with a deflection.

In testimony that I claim the foregoing as my invention', I have signed my name in presence of two subscribing witnesses.
